LC5910S Overview
LC5910S is the buck single-output LED driver IC that achieves the LED drive with few ponents, high efficiency, and high accuracy. The IC has various protections and configures various LED circuits. The PWM dimming and the three-level dimming (the reference voltage selection function for LED current limiting) are available.
